Solange Knowles took a break from her North American tour to stop by The Late Show With David Letterman, performing "Don't Let Me Down" from her new EP True. Awash in polka dots, Knowles delivered a quirky dance track with the bounce and ethereal beauty of the bubblegum and perpetual boy problems era we have cradled close to our hearts since the rise of the Brat Pack. Her refrain of "baby, baby please don't let me down" perfectly compliments the melody of this super-cute ode to an insecure lover - a performance completed by a strong set of backing vocals and a super-tight rhythm section. If you know what's good for you, you'll get tickets to see Solange when she stops in your town.
